RPG Character Classes [Forum Game | Please Contribute :p]

Hi i just want to know how many RPG Character Classes that has ever been made. I hope everyone contributes.

Say the Name of the Character Class, What game has/have you seen it, and a little description of the class. You may post the basic ones such as knight, druid, etc. but i would love it if you can contribute a unique one.

I'll start

Character Class: Psion/Psionicist
Game: Dungeons and Dungeons
Description: Psions seem to be mage-like classes with spells that concentrate on the power of the mind such as Telepathy and Psychokinesis. Though in Dungeons and Dragons, the skills of a psion aren't considered magical but on a separate class of its own, making psionic effects unable to be countered by magic spells and vice versa.

Character Class: Duelist
Game: Seiken Densetsu, Forgotten Realms
Description: In Seiken Densetsu, it is a swordman based class that has powerful sword blows. In forgotten realms, this class is also a sword user however, on the game, duelists rely on speed to deal powerful blows.

Character Class: Paladin
Game: Ragnarok, Seiken Densetsu, Disciples II, Dungeons and Dragons, Diablo II
Description: A character often portrayed as a warrior of the light. He often acts as support, tanker as well as a warrior that uses holy attribute attacks.

Character Class: Dervish
Game: Seiken Densetsu, Forgotten Realms
Description: This character class is almost similar to a berserker that either relies on bare hands or knuckles as weapons but is commonly portrayed as a more elegant class. Rather than pure brute strength, dervishes harness skills that gives them their lethal damage. In Forgotten Realms, this class relies more on speed and has skills that almost resemble a dance.

Character Class: Druid
Game: Diablo, Dungeons and Dragons, World of Warcraft
Description: This character class is almost a mage type character with its spells all related to nature. In most games, druids can summon allies from nature, conjure nature inspired offensive and defensive spells and even transform into beasts them selves to give them various battle capabilities. In such cases, they can be both a powerful mage and a fierce warrior.

Character Class: Knight
Game: Ragnarok, Final Fantasy Tactics Advance, Disciples II, Seiken Densetsu
Description: A very common character class, known for their endurance in taking in vast amounts of damage. They usually function as the team's tanker or front liner as the nukers stand behind to deal powerful blows to the enemy while being protected from damage.

Character Class: Mage/Magician
Game: Ragnarok, Final Fantasy Tactics Advance, Disciples II, Seiken Densetsu, Shining Force II
Description: A basic spell caster class, usually able to cast minor spells in case of RPGs which implement rank up systems. It is a common starter rank for spell caster classes, mostly relying on some simple spells to deal high damage or area of effect damage to enemies.
